Moat63
Equal-weight average of four evidence-backed rubric grades (0–4), scaled to 100.
structural advantage · 3/4 · The current quarry footprint, high truck freight costs, lower-cost rail and water access, and constrained deposit availability establish meaningful local barriers. Comparative cost leadership in every market is unproven.
durability · 3/4 · Existing zoned reserves and difficult replacement supply support durable local advantages, with a disclosed long-lived acquired reserve position. Depletion and continuing permit requirements prevent an exceptional or guaranteed durability assessment.
customer dependency · 2/4 · Economic haul distances and specification requirements can constrain alternative sourcing, but do not establish contractual lock-in. Organic shipment growth offers indirect demand evidence; historically disclosed purchase orders generally lacked firm quantity commitments.
erosion resilience · 2/4 · Organic prices and shipments increased in 2026 despite mix and accounting pressures, supporting ongoing competitiveness. Historical downturn-related volume weakness and actual unrecovered cost pressures show incomplete protection from erosion.
Pricing power56
Equal-weight average of four evidence-backed rubric grades (0–4), scaled to 100.
realized pricing · 3/4 · Organic aggregates ASP rose 2.1% in second-quarter 2026 and 1.7% in the first half while organic shipments also increased. Specialties reported organic pricing gains. Reported aggregates ASP fell with mix changes, and the evidence does not establish exceptional multicycle pricing durability.
retention · 2/4 · Organic aggregates shipment growth alongside higher organic prices indicates continuing demand indirectly. It cannot identify repeat customers or isolate retention from new projects; the absence of firm quantity commitments limits demand security.
margin resilience · 2/4 · Reported 2025 aggregates gross profit per ton improved, but first-half 2026 aggregates gross profit declined with inventory markup charges and higher depreciation, depletion and amortization. Downstream cost and job-margin deterioration and historical cost-recovery shortfalls establish mixed resilience rather than pricing immunity.
contractual freedom · 2/4 · Historically noncommitted purchase quantities and mostly short-term paving contracts indicate limited long-term volume protection and some opportunity to reset terms as work renews. They do not establish unilateral repricing rights; disclosed contract structures can limit or delay adjustments. Comprehensive current terms are unavailable.
Predictability85

Financial strength53
Equal-weight grades: debt/FCF (1–8x), net debt/earnings before interest and tax (0–5x), interest service (1–12x), current ratio (0.75–2x). Earnings use reported operating income, or reported pretax profit plus reported interest expense when operating income is unavailable. Interest service uses earnings/interest expense; if unavailable, it uses reported operating cash flow/cash interest paid, without relabeling cash paid as accrued expense. Nonpositive cash flow/earnings score 0 for their service component; reported zero interest with a positive numerator scores 100. Net cash scores 100 for net leverage. Missing disclosures remain unavailable. General nonfinancial-company rubric, not a credit rating; exceptional and nonoperating gains are not normalized out. IFRS finance-cost and cash-flow classifications retain their reported scope.

Capital allocation79
Three-year equal-weight indicators: pretax return on average invested capital (0–25%; equity + debt − cash, each year and its prior year), share-count growth (0–5%, lower better), share-based cost/revenue (2–20%, lower better), consolidated FCF/net income (0–1x). Return uses reported operating income or, if unavailable, EBIT calculated from reported pretax profit plus reported interest expense; exceptional/nonoperating gains are not normalized out. Share-based cost uses the reported cash-flow add-back or, if absent, separately reported recognized compensation expense; the latter never becomes an FCF adjustment. Nonpositive net income scores 0 for cash conversion; absent income/FCF stays unavailable. Nonpositive invested capital has no defined return and remains unavailable. Does not establish acquisition quality or buyback timing.

Management56
Equal-weight average of four evidence-backed rubric grades (0–4), scaled to 100.
capital discipline · 2/4 · Actual cash generation, capital investment and completed portfolio recycling support an assessable allocation record. First-half 2026 acquisitions and repurchases accompanied net borrowing and lower operating cash flow, partly affected by transaction taxes. Acquisition returns and repurchase value are not established, leaving discipline mixed.
incentive alignment · 3/4 · Actual 2025 long-term awards consisted of 55% PSUs and 45% RSUs, alongside substantial executive and director stock ownership guidelines. These demonstrate meaningful alignment mechanisms, although holdings, compliance, target difficulty and realized vesting are not established; forward PSU targets were confidential.
execution · 2/4 · Completed portfolio transactions, 2025 aggregates profit-per-ton improvement and 2026 organic shipment and pricing growth demonstrate execution through operating evidence. Recent continuing operating earnings declined, and acquisition accounting and downstream weakness complicate evaluation. The evidence supports mixed execution rather than treating management's strategic claims as proven.
governance · 2/4 · Independent committees, adopted majority voting and completed shareholder-responsive severance amendments support accountability. Restrictions on removing directors and calling special meetings constrain shareholder authority, producing a mixed assessment.
Evidence
The Company supplies aggregates (crushed stone, sand and gravel) through its network of approximately 400 quarries, mines and distribution yards in 28 states, Canada and The Bahamas.
Item 1 — Business; operating footprint · Filed 19/02/2026
Proximity of quarry facilities to customers’ plants, construction sites or long-haul transportation corridors is an important factor in competition for the sale of aggregates products.
Item 1 — Business; proximity and competition · Filed 19/02/2026
Generally, the distance shipments travel by truck from a given quarry is limited because the cost of transporting processed aggregates to customers is high relative to the price of the product itself.
Item 1 — Business; truck transportation economics · Filed 19/02/2026
The Company’s distribution system mainly uses trucks, but also has access to rail and waterborne networks where the per-mile unit costs of transporting aggregates are lower.
Item 1 — Business; rail and water transportation costs · Filed 19/02/2026
The Company’s distribution network moves aggregates materials from certain domestic and offshore sources via its long-haul rail and waterborne distribution network to markets where aggregates supply is limited due to geological constraints.
Item 1 — Business; distribution into geologically constrained markets · Filed 19/02/2026
The Company’s rail-based distribution network, coupled with the extensive use of rail service, increases the Company’s dependence on and exposure to railroad performance, including track congestion, crew availability, railcar availability, locomotive availability and the ability to negotiate favorable railroad shipping contracts.
Item 1 — Business; railroad dependence · Filed 19/02/2026
Production costs are generally higher at underground mines than surface quarries because the depth of the aggregates deposits and the access to the reserves result in higher costs related to development, explosives and depreciation costs.
Item 1 — Business; underground mine production costs · Filed 19/02/2026
Quality deposits that meet customer specifications are increasingly difficult to secure near growing markets due to competing land uses, zoning and land-use restrictions, and community opposition.
